An Ansible tutorial is a practical guide that teaches you how to use Ansible, an automation tool, to manage servers and automate tasks. These tutorials usually start with the basics of installing Ansible and writing simple “playbooks,” which are scripts that define the tasks to be automated. You’ll learn to execute these playbooks to manage configurations and deploy software across your servers, making the process efficient and repeatable. The tutorials are designed to be accessible, emphasizing hands-on learning and real-world applications.
Ansible is an automation and orchestration tool. It is software that automates software provisioning, configuration management, and application deployment. The best way to increase my DevOps skills.
Getting Started with Ansible
Start your project
$ mkdir project $ cd project
Create an Ansible Inventory file
~/project/hosts
[webserver] 127.0.0.1 192.168.0.1
List of hosts you want to manage, grouped into groups.(127.0.0.1 deploy your local machine)
Create ansible-playbook
~/project/playbook.yml
- hosts: 127.0.0.1
user: root
tasks:
- name: install nginx
apt: pkg=nginx state=present
- name: start nginx every bootup
service: name=nginx state=started enabled=yes
Ansible run playbook
ansible-playbook -i hosts playbook.yml
Structure ansible role
roles/ common/ tasks/ handlers/ files/ # 'copy' will refer to this templates/ # 'template' will refer to this meta/ # Role dependencies here vars/ defaults/ main.yml
Ansible Modules
Service modules
- service: name: nginx state: started enabled: yes
Install Nginx modules
tasks:
- name: ensure nginx is at the latest version
apt: name=nginx state=latest
- name: start nginx
service:
name: nginx
state: started
Ansible shell
- shell: apt-get install nginx -y
script module
- script: /home/huupv/script.sh
